Mourne Seven Sevens

For anyone who cannot make the official Mourne seven sevens this year, we will run it again this year as a TB event.
For those not familiar with this event, it covers the seven peaks >700m in height in the Mourne mountains. It's approx. 28km and 2,130m ascent. So not for the faint hearted.
Anyone signing up to this hike must be a regular hiker with the TBs and have a good level of fitness. Or convince me you have done similar hikes in the past.
I'll be doing some long hikes over the coming months which will be good training hikes for this.
